The Protective Effect and Molecular Mechanism of Tetrandrine on Male Reproductive Damage Caused by Silicon Dioxide

Toxics
The long-term inhalation of free silica dust causes silicosis—a prevalent occupational hazard—yet its systemic effect on male reproductive toxicity remains underexplored.

Phenotypically Plastic Responses to Predation Risk Are Temperature Dependent [PDF]

, 2019
Predicting how organisms respond to climate change requires that we understand the temperature dependence of fitness in relevant ecological contexts (e.g., with or without predation risk).

Using Morphological Characters to Support Decision-Making in Nature-Based Solutions: A Shortcut to Promote Urban Plant Biodiversity

Urban Science
Cities are particularly vulnerable to climate change for their intrinsic characteristics. Imperviousness, heat islands, and pervasive pollution are common urban problems that challenge the current status quo in decision-making.

Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]

, 2008
The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...

Camel Anatomy; More Than Just a Hump [PDF]

, 2019
The one-humped camel (Camelus dromedarius) is capable of living in extreme, arid environments due to its numerous anatomical adaptations. Its modified features of the muscular system, integument, skeletal system, and several internal organs allow this ...

Floral biology of Sesbania virgata: an invasive species in the Agreste of Paraíba, northeastern Brazil

Rodriguésia
Although reproduction seems to play an important role in the successful invasive strategy of Sesbania virgata, its floral biology is poorly known. We aimed at filling this gap by studying the floral biology of a population of S. virgata in the Agreste of

The role of two anatomically separate olfactory bulbs in shark food odor tracking [PDF]

, 2017
Most sharks have well-developed olfactory systems and depend to a large degree on odor information to locate food, home and navigate, and possibly detect predators and mates.
